Hi folks, new here with less than 2 hours flying time. I see on the forum lots of references to only flying with a full battery. Do you only have one continuos flight. I have on occasions flown for 5-7 minutes landed and switched off changed location, switched back on and recalibrate C Compass and had another flight. I may do this a couple of times each outing. Is this not a good thing to do and if do why?
